Second charge mortgage rates in September 2026 range from approximately 7.5% to 14% APR depending on combined LTV, credit profile, and the lender. That sounds expensive versus a first charge remortgage — and often is. But a second charge is the right answer when: your existing first charge carries a very low rate with a significant ERC; you have a large capital-and-interest mortgage you would lose the benefit of by remortgaging the whole balance; or your income or credit has changed since your original mortgage and you cannot remortgage to the main product range. In those scenarios, the cost of the second charge is lower than the cost of exiting the first mortgage.

| Scenario | Second charge rate | Remortgage cost | Bridging alternative | Winner |
|---|---|---|---|---|
| Existing 2% fix, 2yr ERC £6,000. Need £80,000. | 9.5% APR on £80,000. 5yr cost: £20,900 interest. | ERC £6,000 + new rate 4.80% full balance £300,000. Extra cost vs 2%: £42,000 over ERC period. | 0.80%/month bridge — too expensive for 5yr need. | Second charge wins — avoids ERC and preserves low first charge rate. |
| Existing 4.5% fix, 6m ERC £1,500. Need £50,000. | 10.5% APR on £50,000. Cost: £5,250/yr. | ERC £1,500 + new rate 4.80%. Whole-balance saving modest. | Not suitable for long-term need. | Remortgage wins — small ERC, modest rate difference. |
| No ERC remaining. Need £100,000 capital raise. | 9.0% APR second charge. | Remortgage at 4.70% whole balance. Capital raise route straightforward. | N/A | Remortgage wins — lower total rate, no complexity premium. |
What determines your rate
Combined LTV — the key pricing driver
Second charge lenders assess the combined LTV: the first charge balance plus the second charge amount, divided by the property value. At combined 75% LTV or below, rates are at the lower end. Above 80% combined, the rate premium increases. DBF calculates the combined LTV before approaching lenders and identifies which lenders have the best rates for your specific position.
When second charge beats remortgaging
Three scenarios where second charge wins: (1) Your existing first charge has a low rate (below 2.5%) with a significant ERC remaining. Preserving that rate is worth the higher second charge rate. (2) Your circumstances have changed (income drop, new credit issue) and you cannot get the same terms on a full remortgage as your existing deal. (3) Your existing first charge lender does not allow further advances or charges a high rate for additional lending.
Second charge vs bridging loan
Second charge mortgages are long-term (5–25 year) products. Bridging loans are short-term (1–24 months). If you need capital for a temporary need (tax bill, short-term cash gap, development), bridging is more appropriate. If you need capital for a long-term purpose (home improvement, debt consolidation, business investment), second charge is cheaper over the period. DBF advises on which structure is more cost-effective for your specific need and timeline.
Lender panel for second charges
The main second charge lenders in September 2026 are Pepper Money, West One, Shawbrook Bank, United Trust Bank, and Optimum Credit. Each has slightly different appetite for property type, credit profile, and combined LTV. The second charge market is almost entirely broker-only — lenders do not typically deal directly with borrowers. DBF accesses the full second charge panel.
Worked cost example
- Option A — Second charge
- £90,000 at 8.9% APR over 10 years
- Total cost of additional £90,000
- £43,680
Property value: £450,000. First charge: £200,000 at 1.99% (2020 5yr fix, 2yr ERC remaining at £3,800). Need: £90,000 for home extension.
Combined LTV: (£200,000 + £90,000) / £450,000 = 64.4%. Good LTV band.
Monthly: £1,114. 10yr total interest: £43,680. ERC on first charge: £0.
Option B — Remortgage whole balance £290,000 at 4.75% over 20yr.
ERC: £3,800. Additional interest vs keeping 1.99% first charge (over 2yr remaining)
£290,000 × (4.75%–1.99%) × 2yr = £16,008 extra interest cost.
Total cost of accessing £90,000: £3,800 ERC + £16,008 extra interest = £19,808 in next 2 years.
Second charge total 2yr cost: ~£16,700 interest. Remortgage equivalent cost: ~£19,808.
Second charge saves ~£3,108 over the ERC period — then reassess at ERC expiry.
Rate context and outlook
The second charge market has grown as more borrowers have locked in low fixed rates that they are reluctant to break. With ERC costs often running to £5,000–£20,000 for mortgages taken between 2020–2022, a second charge to access equity without triggering the ERC has become a financially rational choice. DBF models the total cost both ways for every client before recommending.
Frequently asked questions
What is a second charge mortgage?
A second charge mortgage is a loan secured against your property that sits behind your existing mortgage. The first charge lender has priority; the second charge lender ranks second. Second charges allow you to borrow additional money against your property without disturbing your existing mortgage. They are used to access equity when remortgaging the whole balance would cost more due to early repayment charges or changed circumstances.
What are second charge mortgage rates in September 2026?
Second charge rates range from approximately 7.5% to 14% APR depending on combined LTV, credit profile, and term. At combined 75% LTV or below with clean credit, rates start around 7.5%–8.5% APR. Above 80% combined LTV or with adverse credit, rates rise to 10%–14% APR. Named lenders include Pepper Money, West One, Shawbrook, and United Trust Bank.
Is a second charge mortgage cheaper than remortgaging?
It depends on the cost of exiting your existing mortgage. If your existing first charge carries a significant early repayment charge (ERC), keeping it and taking a second charge can save money compared to remortgaging the full balance. DBF calculates the break-even point for your specific situation. Where there is no ERC, a full remortgage is almost always cheaper.
How long does a second charge mortgage take?
Second charge mortgages typically complete in 2–4 weeks, faster than a full remortgage. The process involves a valuation, credit assessment, and legal documentation — but as the existing first charge does not change, conveyancing is simpler. Regulated second charges require a 7-day reflection period.
Do I need my first charge lender's permission for a second charge?
Your first charge lender does not formally need to give permission, but they are notified as a standard part of the second charge legal process. Some mortgage conditions restrict additional secured borrowing — check your existing mortgage terms. DBF reviews your existing mortgage documentation as part of the second charge assessment.
